Various derivatives of (R)-1-(1-naphthyl)ethylamine have been synthesized and tested as chiral modifiers of Pt/alumina in the enantioselective hydrogenation of ketopantolactone. The best modifiers (ee up to 79%) possess an ester function in the a-position to the amino group. The modifiers performed

Inversion of enantioselectivity in the hydrogenation of ketopantolactone on platinum modified by ether derivatives of cinchonidine

Asymmetric hydrogenation of ketopantolactone was studied on a 5 wt% Pt/Al 2 O 3 catalyst in the presence of cinchonidine and its O-methyl, -ethyl, -phenyl and -trimethylsilyl derivatives. Inversion of enantioselectivity with the latter two bulky substituents proved that in the enantiodifferentiating
